Neco 2020 Data Processing Question 33

An educational institute allocates a total ICT budget of \(\text{₦}500{,}000\) to four classes (A, B, C, D). The number of students and the sum of their test scores are: - Class A: 45 students, total score 3,240 - Class B: 38 students, total score 2,850 - Class C: 50 students, total score 3,800 - Class D: 42 students, total score 3,150 The average score of a class is the total score divided by the number of students. The class with the highest average receives 30 % of the budget, the class with the second‑highest average receives 20 % of the budget, and the remaining two classes share the rest equally. If two classes have the same average, the class with more students is ranked higher. Determine the amount (in naira) allocated to each class.
